PICKLING MACHINE;-

'- To' all whom it may concern:

g and State of Be it known that I, WARREN G. LEINBACH, a citizen of the United States, and a resident of VVilkinsbur r, in the county of Allegheny fiennsylvanimhave invented a new and useful Improvement in Pickling Machines, of which'the following is a specification.

The invention relates to that. type of p1ckling machines which include a plurality of vats and mechanism for reciprocating the articles being treated in the vats, and forplacing the articles in and from the vats.

The object of the invention is to provlde a pickling machine of the general character removing them explained which will be simple in construction, effective-in operation and economical to manufacture. invention 1s to provide a pickling machine in which thereciprocation of the articles.

being treated in the vats and the removal of the articles from the vats is effected by independent motors and driving connectlons of simple design. The invention is illustrated in the accompanying sheets of drawings, of. which F ig. 1

is a combined elevation and vertical central sectional view of the complete apparatus- Figs. 2, 3 and 4 horizontal sectional views to enlarged scale taken, respectively, on the lines 11 11, 111' 111 and 1v ,1v, Fig. 1;.

and Fig. 5 a side view of an intermediate portion of the ram, the plane of View being indicated'by the line V-V, Fig. 1.

In pickling machines of the character contemplated herein, three pickling vats '1,

are usually arranged at quarter points arounda verticallymovable ram 2. Two of such vats are indicated in Fig. 1,,u1e position of the third usually being immediately back of-the ram. The fourth quarter point is usually used for a loading and unloading station. In the practice of the invention, the ram I 2 is preferably formed of an H-section, the

lower end of which extends into a well 8 below the floor level 5. At the upper end of the ram there are a plurality of laterally extending arms 6, fromthe outer ends of which cages 7 are suspended by means of rods or cables 8. The arms 6, of which there are preferably four in number, form a spider having a central hubv 9 rotatably mounted on a cap 10 secured to the top of:

the ram. Preferably, a race of ball bear- Specificat-ion of Letters Patent. Application filed March 26, 1921.

in gs 11 is arranged between the cap low and i hub 9. By this construction, the spider may be readily rotated upon the other Whenthe ram is in to support the cages above vats.

. While the cages are in'the vat in the positions indicated in Fig. 1, they are vertically reciprocated to circulate the acid bath,water or other treating liquid in the vats and upon the facesof the articles. For this purpose,

the tops of the top of the ram to move the cagesfrom one station to an-.

such position as a.

an arm 12 is pivoted, preferably at its outer web of the ram 2 andpro therefrom. The collar 16,

so that, when the collar-is reciprocated, the 7 ram will move owever the connection is such that the ram 2 may be moved upwardlyindependentlyof themovement of collar 16, as will presently be explained.

or reciprocating arm 12, an electric mo-- tor 18 I v frame 14, and suitable arranged between; the motor and arm. In the illustrated embodiment f the invention, the driving connections include apinion 19 connected to the armature shaft and mesh-' ing withapinion 20"mounted on a rotatable crank shaft 21, towhich there is attached a pitman 22 pivotally connected as at 23 to arm 12. By such connections, the continuupwardly and downwardlymay be mounted upon the base of i ous rotationof the motor effects a continu-- ous oscillation of;-the arm, which in turn causes continuous reciprocation-of the ram.

The vertical movement of the ram 2 to remove the'cages from the vats'is driving connections between. itand the'ram.

he motor for this purpose may. be anielee trio. motor 24-mount d on the base offrame 1 To the armature shaft of the motor, there is connecteda pinion 25 Which drives a pinion 26 securedto a rotary shaft 27 pro vided with a pair of sprocket wheels '28 arranged one on each side of ram 2. Around prefer- 1 ably effected by a separate, motorand suitable each sprocket wheel there is a chain 29, the lower end of which is attached to a base 30 at the lower end of the ram. By operating the motor 2%, the sprocket wheels 28 may be rotated to either elevate or lower ran'i2. The free end of chains 29 may pass around rollers 31, arranged in well 3, as seen in Fig. 1.

To hold the ram in its vertical position, suitable guides are provided. To avoid friction, such guides may take the form of a pair of oppositely disposed rollers 32 mounted on the top of frame li, a roller 33 mounted on rotary shaft 27, and a roller 34: ar ranged in the upper end of well 3 in a position substantially opposite to the roller 33.

In the operation of the pickling machine, assuming that the cages have been filled with material to be treated and that the apparatus is in the position indicated in Fig. 1, motor 18 may be operated to cause the ram 2 to reciprocate. The driving connections from the motor include pinions 19 and 20, crank shaft 21, pitman 22, pivoted arm 12, links 15, collar 16 and brackets 17. At the end of a pickling operation, the motor 18 may be stopped and motor 2% operated to elevate the ram 2 to such position that the lower edges of the cages are above the upper edges of the vats. The driving connections for this purpose includepinions 25 and 26, rotary shaft 27, sprocket wheels 28, chains 29 and a base 30 upon which the ram rests. When the ram has been elevated to the proper position, the cages may be engaged by hand and pulled so as to cause the spider to rotate upon the upper end of ram 2. he rain may then be lowered by using motor 24 as a brake, after which motor 18 may be again started in operation to re ciprocate the ram.

According to the provisions of the patent statutes, I have described the principle and operation of my invention, together with the construction which I now consider to represent the best embodiment thereof. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced by other forms of construction than that specifically shown and described.
